IMPROVEMENT IN FORKS.

Specification forming part of Letters Patent No. 218,642, dated August19, 1879; application filed May 26, 1879.

To all whom it may concern.-

Beit known that I, CHARLES W. RoBIsoN, of Allegheny, in the county ofAllegheny, State of Pennsylvania, have invented a new and usefulImprovement in Forks; and I do hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in forks and consists in makingthe teeth detachable, and secured in a head-piece or bar constructed iutwo parts, the lower part being provided with openin gs for theinsertion of the teeth, which are coniformed, or tapering from the headltoward the point, and suitablycurved, the openings in the lower part ofsaid headbar corresponding to the form and diameter of the upper end ofsaid teeth.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification,Figure l is a perspective view of my improved fork. Fig. 2 represents alongitudinal central section through the head of the fork, andcorresponding section through the handle.

In the drawings, A B represent the headbar, the part B being providedwith openings.

corresponding in size and form to the upper end of the teeth G. The partA is provided with a socket, D, for the reception of the handle e, whichis constructed of wood, and made in any of the known forms, and securedin the socket by any of the known means. The part A is secured to thepart B by means of screwnuts or screws, as at j', thereby holding .theteeth in position in the part B.

The teeth are made Of steel, and of any of the known forms. Thehead-piece, consisting of the parts A and B, may be made of Wroughtironor of malleable cast-iron.

The advantages of my improvement are simplicity of construction, withfacility of repairing in case of any of the teeth being broken orotherwise disabled, and the fork may be renewed by simply providing itwith new teeth.

What I claim as my invention is- The herein-described fork, consistingof the headbar A B and detachable teethV C, the portion B of the headprovided with tapering openings through it, corresponding in size andform to the upper tapering end of the teeth C, and the part A of thehead provided with a socket for the handle, said portions A and Bdetachably connected together, substantially as and for the purposespecified.
